Article abstract of DOI:10.1055/s-0032-1316827

Regiodivergent synthesis of allenes and acetylenes was established in the reduction of propargylic phosphates. The palladium(0)-catalyzed reduction of secondary propargylic phosphates with samarium(II) iodide gave allenes or acetylenes by tuning proton sources (tert-butyl alcohol or dimethyl L-tartrate).
